Six RC beam-column subassemblages, consisting of two single-bay beams, one middle joint, and end column stubs, were quasi-statically tested under a removal scenario. The tests aimed at investigating whether there are alternate load paths that can mitigate progressive collapse. With adequate axial restraints, both compressive arch action (CAA) catenary could be mobilized, significantly increasing the structural resistance beyond beam flexural capacity. effects top bottom reinforcement ratios...
Previous research work has found that catenary action can significantly increase structural resistance in addition to flexural capacity under column removal scenarios. However, whether reinforcements beams effectively function as ties develop against progressive collapse is a big concern current engineering practice because of the limited rotational RC beam-column connections. Therefore, four frame specimens were designed and tested investigate their behavior scenario. In specimen with...
Several structural collapse incidents indicate that failure usually starts from beam-column joints exposed to abnormal loads, especially for steel and composite structures. If the connections are sufficiently robust there is adequate axial restraint adjoining structures, catenary action forms in beams slabs, causing alternate load paths when affected columns severely damaged, resulting large deformations slabs. This paper presents experimental results of bolted-angle under a middle...
Compressive arch action (CAA) is a favourable structural mechanism to mitigate progressive collapse of reinforced concrete (RC) frames. To quickly and accurately predict the CAA capacity RC sub-assemblages under column-missing scenario, an engineering analytical model proposed. The considers all design parameters in beams imperfect boundary conditions sub-assemblages, including partial axial rotational restraints, connection gaps at beam ends if any. proposed then validated with experimental...
